The goal of this clinical medicine study is to investigate how does antidepressant fluoxetine modulate anger processing in healthy young people . The main questions it aims is to answer are:
1. How does fluoxetine affect responses to anger-related stimuli such as words, faces, and autobiographical recall?
2. How does fluoxetine influence responses during frustration induction in frustrative non-reward and threat paradigms?
3. Does the effect manifest in physiological markers, including heart rate variability and facial expressions?
Researchers will compare fluoxetine to a placebo to see if drug fluoxetine affects anger processing.
Participants will:
Take 20mg fluoxetine or a placebo every day for 7 days. Visit the university site for questionnaire and tasks assessments. Heart rate variability and facial expressions will be recorded in some of the tasks.
